https://felib.fujielectric.co.jp/download/login.htm?site=global&lang=en Japanese Guideline for Suppressing Harmonics in Home Electric and General-purpose Appliances Fuji three-phase 200 V class series of inverters with a capacity of 3.7 kW (5 HP) or less, single-phase 200 V class series with 2.2 kW (3 HP) or less, and single-phase 100 V class series with 0.75 kW (1 HP) or less were once subject to the "Japanese Guideline for Suppressing Harmonics in Home Electric and General-purpose Appliances" (established in September 1994 and revised in October 1999), published by the Ministry of International Trade and Industry (currently the Ministry of Economy, Trade and Industry (METI)) Since the revision of the guideline in January 2004, however, these inverters have no longer been subject to the guideline The individual inverter manufacturers have voluntarily employed harmonics suppression measures As our measure, it is recommended that DC reactors (DCRs) authorized in this manual be connected to the FRENIC-Mini series of inverters When using DCRs not authorized in this manual, however, consult your Fuji Electric representative for the detailed specifications Japanese Guideline for Suppressing Harmonics by Customers Receiving High Voltage or Special High Voltage Refer to the FRENIC-Mini User's Manual (24A7-E-0023), Appendix C for details on this guideline i Safety precautions Read this manual thoroughly before proceeding with installation, connections (wiring), operation, or maintenance and inspection Ensure you have sound knowledge of the device and familiarize yourself with all safety information and precautions before proceeding to operate the inverter Safety precautions are classified into the following two categories in this manual Failure to heed the information indicated by this symbol may lead to dangerous conditions, possibly resulting in death or serious bodily injuries Failure to heed the information indicated by this symbol may lead to dangerous conditions, possibly resulting in minor or light bodily injuries and/or substantial property damage Failure to heed the information contained under the CAUTION title can also result in serious consequences These safety precautions are of utmost importance and must be observed at all times Application • FRENIC-Mini is designed to drive a three-phase induction motor and three-phase permanent magnet synchronous motor (PMSM) Do not use it for single-phase motors or for other purposes Fire or an accident could occur • FRENIC-Mini may not be used for a life-support system or other purposes directly related to the human safety • Though FRENIC-Mini is manufactured under strict quality control, install safety devices for applications where serious accidents or material losses are foreseen in relation to the failure of it An accident could occur Installation • Install the inverter on a nonflammable material such as metal Otherwise fire could occur • Do not place flammable matter nearby Doing so could cause fire ii • Do not support the inverter by its terminal block cover during transportation Doing so could cause a drop of the inverter and injuries • Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the inverter or from accumulating on the heat sink Otherwise, a fire or an accident might result • Do not install or operate an inverter that is damaged or lacking parts Doing so could cause fire, an accident or injuries • Do not get on a shipping box • Do not stack shipping boxes higher than the indicated information printed on those boxes Doing so could cause injuries Wiring • When wiring the inverter to the power source, insert a recommended molded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) (with overcurrent protection) in the path of power lines Use the devices within the recommended current range • Use wires in the specified size • When wiring the inverter to the power supply of 500 kVA or more, be sure to connect an optional DC reactor (DCR) Otherwise, fire could occur • Do not use one multicore cable in order to connect several inverters with motors • Do not connect a surge killer to the inverter's output (secondary) circuit Doing so could cause fire • Be sure to connect the grounding wires without fail Otherwise, electric shock or fire could occur • Qualified electricians should carry out wiring • Be sure to perform wiring after turning the power off • Ground the inverter in compliance with the national or local electric code Otherwise, electric shock could occur • Be sure to perform wiring after installing the inverter body Otherwise, electric shock or injuries could occur • Ensure that the number of input phases and the rated voltage of the product match the number of phases and the voltage of the AC power supply to which the product is to be connected Otherwise fire or an accident could occur • Do not connect the power source wires to output terminals (U, V, and W) • Do not insert a braking resistor between terminals P (+) and N (-), P1 and N (-), P (+) and P1, DB and N (-), or P1 and DB Doing so could cause fire or an accident iii • Generally, control signal wires are not reinforced insulation If they accidentally touch any of live parts in the main circuit, their insulation coat may break for any reasons In such a case, an extremely high voltage may be applied to the signal lines Make a complete remedy to protect the signal line from contacting any hot high voltage lines Doing so could cause an accident or electric shock • Wire the three-phase motor to terminals U, V, and W of the inverter, aligning phases each other Otherwise injuries could occur • The inverter, motor and wiring generate electric noise Take care of malfunction of the nearby sensors and devices To prevent the motor from malfunctioning, implement noise control measures Otherwise an accident could occur Operation • Be sure to install the terminal block cover before turning the power on Do not remove the cover while power is applied Otherwise electric shock could occur • Do not operate switches with wet hands Doing so could cause electric shock • If the retry function has been selected, the inverter may automatically restart and drive the motor depending on the cause of tripping (Design the machinery or equipment so that human safety is ensured after restarting.) • If the stall prevention function (current limiter), automatic deceleration, and overload prevention control have been selected, the inverter may operate at an acceleration/deceleration time or frequency different from the set ones Design the machine so that safety is ensured even in such cases Otherwise an accident could occur • The STOP key is only effective when function setting (Function code F02) has been established to enable the STOP key Prepare an emergency stop switch separately If you disable the STOP key priority function and enable operation by external commands, you cannot emergency-stop the inverter using the STOP key on the built-in keypad • If an alarm reset is made with the operation signal turned on, a sudden start will occur Ensure that the operation signal is turned off in advance Otherwise an accident could occur iv • If you enable the "restart mode after momentary power failure" (Function code F14 = or 5), then the inverter automatically restarts running the motor when the power is recovered (Design the machinery or equipment so that human safety is ensured after restarting.) • If you set the function codes wrongly or without completely understanding this instruction manual and the FRENIC-Mini User's Manual, the motor may rotate with a torque or at a speed not permitted for the machine An accident or injuries could occur • Do not touch the inverter terminals while the power is applied to the inverter even if the inverter stops Doing so could cause electric shock • Do not turn the main circuit power on or off in order to start or stop inverter operation Doing so could cause failure • Do not touch the heat sink or braking resistor because they become very hot Doing so could cause burns • Setting the inverter to high speeds is easy Before changing the frequency (speed) setting, check the specifications of the motor and machinery • The brake function of the inverter does not provide mechanical holding means Injuries could occur EMC filter built-in type • When the wiring length between the inverter and motor exceeds 10 m (33 ft), the filter circuit may be overheated and damaged due to increase of leakage current To reduce the leakage current, set the motor sound (carrier frequency) to kHz or below with function code F26 Otherwise a failure could occur v Maintenance and inspection, and parts replacement • Turn the power off and wait for at least five minutes before starting inspection Further, check that the LED monitor is unlit, and check the DC link bus voltage between the P (+) and N (-) terminals to be lower than 25 VDC Otherwise, electric shock could occur • Be sure to carry out daily and periodic inspections given in the instruction manual Running the inverter without inspections for a long time could result in an inverter failure, breakage, accident or fire • Recommended periodic inspection interval is once to twice a year; however, shorten the inspection interval depending upon the running conditions • It is recommended that periodical replacement parts be replaced according to the standard replacement intervals given in the instruction manual Running the inverter without replacement for a long time could result in an inverter failure, breakage, accident or fire • The contact output [30A/B/C] uses a relay which could stick to ON, OFF or ambiguous state if the service life has expired For safety, provide an external protection function Fire or an accident could occur • Maintenance, inspection, and parts replacement should be made only by qualified persons • Take off the watch, rings and other metallic matter before starting work • Use insulated tools Otherwise, electric shock or injuries could occur Disposal • Handle the inverter as an industrial waste when disposing of it Otherwise injuries could occur Others • Never attempt to modify the inverter Doing so could cause electric shock or injuries GENERAL PRECAUTIONS Drawings in this manual may be illustrated without covers or safety shields for explanation of detail parts Restore the covers and shields in the original state and observe the description in the manual before starting operation vi Conformity to the Low Voltage Directive in the EU If installed according to the guidelines given below, inverters marked with CE are considered as compliant with the Low Voltage Directive in Europe The ground terminal G should always be connected to the ground Do not use only a residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB)* as the sole method of electric shock protection Be sure to use ground wires whose size is greater than power supply lines * With overcurrent protection When used with the inverter, a molded case circuit breaker (MCCB), residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) or magnetic contactor (MC) should conform to the EN or IEC standards When you use a residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) for protection from electric shock in direct or indirect contact power lines or nodes, be sure to install type B of RCD/ELCB on the input (primary) of the inverter if the power source is three-phase 200/400 V For single-phase 200 V power supplies, use type A When you use no RCD/ELCB, take any other protective measure that isolates the electric equipment from other equipment on the same power supply line using double or reinforced insulation or that isolates the power supply lines connected to the electric equipment using an isolation transformer The inverter should be used in an environment that does not exceed Pollution Degree requirements If the environment conforms to Pollution Degree or 4, install the inverter in an enclosure of IP54 or higher Install the inverter, AC or DC reactor, input or output filter in an enclosure with minimum degree of protection of IP2X (Top surface of enclosure shall be minimum IP4X when it can be easily accessed), to prevent human body from touching directly to live parts of these equipment To make an inverter with no integrated EMC filter conform to the EMC directive, it is necessary to connect an external EMC filter to the inverter and install them properly so that the entire equipment including the inverter conforms to the EMC directive Do not connect any copper wire directly to grounding terminals Use crimp terminals with tin or equivalent plating to connect them To connect the three-phase or single-phase 200 V class series of inverters to the power supply in Overvoltage Category III or to connect the three-phase 400 V class series of inverters to the power supply in Overvoltage Category II or III, a supplementary insulation is required for the control circuitry When using inverters at an altitude of more than 2000 m (6600 ft), note that the basic insulation applies to the insulation degree of the control circuitry At an altitude of more than 3000 m (9800 ft), inverters cannot be used 10 The power supply mains neutral has to be earthed for the three-phase 400 V class inverter 11 The inverter has been tested with EN61800-5-1 5.2.3.6.3 Short-circuit Current Test under the following conditions Short-circuit current in the supply: 10 kA
